Because of the perch bite, the heads of the Richard J. Daley Sportfishing Derby added perch to the eligible species for August.
There were so many nice perch coming in that the decision seemed logical.
The derby runs through Sept. 30. Register fish at Henry's Sports & Bait, Park Bait or Vet's Bait. Go to henryssports.com or call (312) 225-8538.
Other species in August are carp, catfish, panfish, steelhead and chinook.
Perch have opportunistic mouths.
